Abstract: 610,057. Multiple-way valves. JONGERIUS N. V., J. Oct. 25, 1945, No. 28168. Convention date, Sept. 17, 1943. [Class 135] A multiple-way valve for controlling the supply and exhaust of liquid to several hydraulic motors comprises a housing 1 with ducts 7, 8, 9, 10, 11, 12 leading to the motors and ducts 5, 6 leading from and to a pump or the like, and a rotary plug 2 with ports and passages for selectively connecting the motor ducts to the pump, each motor duct having a check valve 14 seating radially towards the plug and opened by a lifting device in the plug actuated or controlled by a separate movement of the plugactuating means after selection of the motor to place one of the ducts of the selected motor in communication with the suction side of the pump. The check valve of the other selected duct is then opened automatically by the pressure from the pump. On releasing the lifting device, the motor is locked by the check valves in its adjusted position. As shown, the check valves comprise spring-loaded ball valves 14 and diametrically opposite pairs of ducts 7, 10; 8, 11; and 9, 12 are connected to three hydraulic motors. The lifting device comprises a radially sliding dog or projection 25 moved outwards against a spring 27 by the bevelled lower end 26 of a valve rod 20 moved axially within the plug against a spring 21 by a lever 23. The latter is pivoted in a slot in the top of the plug and serves also for turning the latter. The valve rod 20 has a reduced part 22 which in the raised position of the lever 23 connects a supply passage 17 with an exhaust passage 18. The passages 17, 18 open opposite pairs of ducts 7, 10, &c. when the plug is turned. The passage 17 is permanently connected with the supply duct 5 from the pump by an annular groove 15 whilst a similar annular groove 16 permanently connects the passage 18 with the duct 6 leading to the suction side of the pump. In a modification, the dog 25 is actuated hydraulically by a spring-loaded differential piston subject on its opposite sides to the pressures in the passages 17, 18.

Abstract: 965,025. Erecting folding tower-cranes. ETABLISSEMENTS F. POTAIN & CIE. July 25, 1962 [July 31, 1961; Oct. 13, 1961], No. 28529/62. Heading B8B. A folding tower crane is erected by attaching the lifting hook to the base 1, Fig. 2, with the crab 9 near the outer end of the jib and by means of the lifting cable 15 maintaining the jib horizontal against a tendency to rise caused by a counterweight 7 whilst the tower 4 is raised to a vertical position by a winch 10 and cable 11. In a first embodiment the load hoisting winch is locked and as the tower is raised the crab 9 is displaced inwardly to maintain the jib horizontal. In a second embodiment, Figs. 5-7 (not shown), the crab 9 is held near the outer tip of the jib and the load hoisting winch is operated to pay out the hoisting cable thereby holding the jib horizontal as the tower is raised. In a further embodiment, Fig. 8, the lifting hook is attached to the base 1 as before and the tower is partly raised so that the counter-jib 23 can be swung out from under the tower and then lowered so that the counter-jib reaches the position shown in Fig. 10. In this position a cable 29 is connected between an upright 27 and the counter jib 23 and the jib is connected to the upright 27 by a tie-rod 28. The tower is now raised by the winch 10 and the jib is maintained horizontal by either of the methods described above. During this step a post 6 rises progressively and a pulley 25 engages the cable 29. At the end of this movement a locking hook 30, Fig. 13, rides up over a pin 27a and drops down to engage it thereby uniting parts 6 and 27. After the parts have been locked together by conventional means, and the hook 20 freed from the base, the telescopic part of the tower is raised. The cranes described in the first and second embodiments may also have telescopic towers.

Abstract: 351,354. Two-way repeaters. VIARD, G., 254, Rue de Vaugirard, Paris. Sept. 29, 1930, No. 29182. Convention date, Nov. 13, 1929. [Class 40 (iv).] A delay device which may be an electrical network or may involve magnetic or other recording is so arranged that the retardation it imposes is gradually diminished to zero as the transmission proceeds. As shown, communication currents arriving from 1 are recorded by the apparatus 5 on a rotating magnetic disc and are retransmitted by the apparatus 6 acting on its opposite face shortly afterwards. Control currents transmitted from 2 on the arrival of the communication current energize relays ,10, 15. The latter, which operates sluggishly, causes the pick-up to be rotated in the opposite direction to the disc by means of a magnetic clutch 14 thereby reducing the delay time until, when the recorder and pick-up are in the same angular position, contact springs 8 energize relay 9 which cuts out the delay device and locks itself up. At the same time a relay 16 cuts off 15, the arrangement being such that the pick-up proceeds to its normal position but cannot be coupled up again until relays 9, 10, 16 have been released.
